Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at mu-opioid receptors, modulating pain perception via central and peripheral pathways.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity by blocking serotonin reuptake into presynaptic neurons.
Immediate-release: 4-8 mg orally every 4-6 hours as needed for pain; extended-release: 8 mg orally every 12 hours, titrated based on response and tolerance.
25 mg orally twice daily

Terminal elimination half-life is approximately 18 hours (range 12-24 h); supports extended dosing intervals.
Terminal elimination half-life: 6-8 hours in adults; may be prolonged (up to 12 hours) in elderly or patients with renal impairment (CrCl <30 mL/min).
Primarily renal (90%) as unchanged drug and glucuronide conjugate; ~10% biliary/fecal.
Primarily renal excretion of unchanged drug (70-80%); fecal elimination accounts for 15-20% via biliary excretion; less than 5% as metabolites.
